WebProofreading. Proofreading is the final stage of the editing process, focusing on surface errors such as misspellings and mistakes in grammar and punctuation. You should proofread only after you have finished all of your other editing revisions. WebThe DNA-polymerase can only add nucleotides on an existing strand of DNA, so the primer (located at ori - origin of replication) "fakes" a DNA strand with a couple of RNA nucleotides. It's just to get things going. The primer is always broken down and replaced by DNA at the end of the replication process.
